The only useful way to increase lean angle is to push more on the inside bar. 44 degrees of lean is fairly easy.
Interestingly, it is theoretically less effort to lean over a sit-up and beg bike, such as an MS than it is a full-on race bike. This is due to the effect of having a bigger lever to use against the gyroscopic effect of the spinning wheels.
Understand why you’d say that, but not sure that’s true in practice. You have arms higher and wider, so can apply less pressure as you push forward, whereas if your arms are a little closer and lower you push out more so can use more force ime. Plus additional weight. Try getting a multi side to side thru a chicane at speed! Otherwise, everyone would run higher bars in sports bikes.
Smaller bars mean less input required for steering changes. Wider bars require more input but that input is easier.
It's a pub conversation we would all make valid points as you have, I've come across enough horseshitters to last a lifetime, the man or woman on the seat makes the difference. Yes when the the riding gets fast limitation of kit comes in but certainly I have rarely seen a good standard sportsbike been pushed to its limit, witham and shoey used to use a srad 750 years ago looked like road kit removed and slicks put on and I couldn't get near it nobody could what I saw.
I think the way you have set the question up implies that this is a constant radius corner and the bike is in a stable state whereby you are accelerating just enough to compensate for the speed scrubbing off due to frictional and other forces so that your speed is a constant 80mph. Under these circumstances, I believe that simple physics suggests that to increase corner speed you will need to lower your combined (bike plus rider) CoG in some way; either by hanging off more or by leaning the bike further or both. Until finally, your courage or friction desert you... As others have said, I don't think the foregoing will do much to help you corner faster!
Experience gives feel to get maximum from what you have and I’d imagine whit and co had plenty!! Likely it would have as a min oil level and change and springs which can make huge difference on their own. And some tracks, like roads, are easier with standard stuff than other tracks and roads.
If a rider was going round Luffield with their pegs scraping, elbow and knee down (not me to be clear), so bike and rider are at max lean. Is it possible to go faster? Can they keep the same line by just asking more of the tyres and suspension until it finally let's go? Or for a given lean and COG and tyre grip (frictuon) is there a set speed?
If a rider gets their body position, steering input, suspension settings all perfect on a given corner, the limitation will be the grip of the rubber. However if you said for the sake of argument that you have "special rubber" that never gives up its grip, the geometry of the tyre becomes the limiting factor, once it can no longer transmit steering force to the road - i.e. you are sliding on your side. It would be hard to test this limit with regard to tyre and bike set-ups, as grip will be the limiting factor in the real world.
At that point it’s up to the tyres. The rider could try a number of things to gain a tiny bit more grip (and therefore be able to ask for more speed). They could adjust their braking/entry to make the tyres more stable mid corner. They could adjust setup to make the tyres more stable. Theoretically there will be a maximum speed for a corner but it’s got so many variables.
Oh, and real world. That’s normally a classic. In the real world, can you go faster for the same lean angle thru the same corner with the same tyres and grip by clenching ones buttocks, or is there a point where buttock clenching and grip runs out?
